London - Viagra is best tested in the privacy of the home, according to middle-aged couples who agreed to appear on British TV as part of an experiment with the anti-impotence drug yesterday.
Mr Derek Brown, one of three husbands aged between 50 and 63 who swallowed the drug on camera, left with his wife for a hotel, then returned an hour later to tell viewers he was delighted with the result.
Mr Alec Witherington, who had tried two other impotence cures, said: "Of the three I think Viagra was the best, but you need to try it in your own home."
